NOTICE :

1.Separately wire the high and low voltage line.

2.Use heat-proof electrical wiring capable of withstanding temperature up to 75°C(167°F).

3.Use outdoor and waterproof connection cable rated more than 300V for the connection between indoor and outdoor unit. (For example, Type SJO-WA)

WARNING:

Be sure to comply with local codes while running the wire from the indoor unit to the outdoor unit(size of wire and wiring method, etc).

Every wire must be connected firmly.

No wire should be allowed to touch refrigerant tubing, the compressor or any moving parts.
